Islaam has come to complete and perfect good character but unfortunately many of us have yet to acknowledge this (behavioral) completeness that Allah has blessed upon the Muslims. Due to this I wanted to (share) some of the legislative treasures and topics related to good character.

Verily the most beloved of you to me and the closest from amongst you to me on the Day of Judgement will be the best of you in character, wihle the most hated of you to me and the farthest from amongst you to me on the Day of Judgement will be those who talk excessively, the loud-mouthed and vulgarly flagrant individuals. [Collected by at-Tirmidhee and graded authentic by al-Albaanee]

Imaam at-Tirmidhee (rahimahullah) said:

Al Mutashaddiq refers to the one who excessively speaks about people in a filthy manner.

Condemnation (and humiliating people) is also something which is dispraised by the Islaamic legislation. The Propet ﷺ said:

If a slave girl commits fornication you must (first) verify and confirm that she has done so. If confirmed, flog her and do not condemingly humiliate her. Then if she commits fornication flog her and do not condemingly humiliate her. [Collected by al-Bukhaaree]

Concealing the sins of others is from the Sunnah of the Messenger ﷺ. He ﷺ used to conceal people's faults as well as assist in the concealment of faults.

A man came to the Prophet ﷺ and said O Messenger of Allah I have transgressed and sinned so establish the legal punishment upon me. Anas (radi Allahu anhu) said then the salaat came in so the man prayed with the Messenger of Alah (and the believers). After the salaat the man again said, "O Messenger of Allah I have transgressed and sinned so establish the legal punishment found in the book of Allah upon me." The Messenger of Allah said, "Did you pray with us?" The man said, "Yes". The Messenger of Allah said, "Verily Alah has already forgiven you." [Collected by Muslim]

Another good character trait is fulfilling the rights of the neighbor even if the neighbor is a non-Muslim.

On the authority of Mujaahid (rahimahullah), a sheep was slaughtered for the family of 'Abdullah Bin 'Umar (radiAllahu 'anhu) when Ibn 'Umar (radiAllahu 'anhu) came (home) he asked, "Did you give some to our Jewish neighbor? Did you give some to our Jewish neighbor? I heard the messenger of Allah ﷺ saying ,"

I have been advised about the rights of the neighboor until I thought that he would inherit from me.

Islaam also prohibits and warns against deception and cheating. The most high says,

But the evil plot encompasses only him who makes it.

So he who is afflicted with being the recipient of someone's deceptive evil plot must be patient and know that the final affair will be for the one who fears Allah. Just like that which has taken place with Yusuf (alahi salaam), there was not for him except to be patient (which he was) and for him (alaihi salaam) was the final affair. So he who is afflicted by something of deceptive evil plots must be patient and kow that the final affair will be for the one who fears Allah; and know that evil plots only encompass (and truly harm) the evil plotters. And you will not find any change or alteration to Allah's Sunnah.
